Description

[Detailed Description of the Invention] This invention relates to a measuring rice jug that automatically measures and discharges the rice in the rice jug body by operating a lever, and more specifically, it relates to improvements in the measuring box and the operating lever.

Conventionally, this type of measuring rice jug consists of a rice jug main body consisting of an outer housing of the rice jug and a decorative board fixed to a notch in the front of the outer housing of the rice jug, and the front of the decorative board has an operation panel connected to the measuring box. A plurality of levers (usually 3 levers) are arranged in parallel according to changes in the discharge amount (for example, every 1st, 2nd, and 3rd cup), and by pressing each lever, a predetermined amount of rice is discharged. was. In other words, two fixed shafts are installed horizontally at the top and bottom between both side walls of the measuring cell main body case, which forms a measuring chamber with the shutter, and the shutter is pivotally supported on the lower fixed shaft, and the lower end of the shutter is normally used for measuring. A spring is wound around the main body case to urge it to come into contact with the rear wall of the main body case, while an operating lever is rotatably pivoted to the upper fixed shaft, and a spring for returning the operating lever is provided. When the upper pressing part of the operating lever is pressed, the operating part at the lower part of the operating lever uses the pivot point with the upper fixed shaft as a fulcrum to press the outer surface of the shutter, opening the discharge port of the metering chamber and dispensing a predetermined amount of rice. It has a structure that allows it to be discharged.

However, this method requires a plurality of operating levers to be pivoted to the upper fixed shaft in response to changes in the discharge volume, and has the disadvantage that the mounting space for the operating levers becomes large. In addition, with the operating lever of this configuration, if the pushing operation part is made longer from the pivot point, the operation of the operating lever becomes easier, but the operating lever itself becomes larger and the rice bin to which it is attached becomes larger, which is a disadvantage. . Therefore, in order to prevent the main body of the rice bin from becoming too large, the distance between the pressing part of the operating lever and the pivot point is made as short as possible, so the operation of the operating lever is quite heavy. Furthermore, when changing the discharge capacity, multiple control levers are installed in parallel and horizontally, so the rice bin itself has to be wide. There was a difficult inconvenience.

This invention solves the above-mentioned conventional inconveniences with a simple configuration, and enables one or more measuring chambers to be operated with one operating lever to dispense different volumes of rice. In addition, the installation space for the operating lever is reduced, and the operating lever can be operated easily.One embodiment of this invention is described below based on FIGS. 1 to 6. explain.

Now, if the large measuring chamber 13 is set to dispense 2 cups of rice, and the small measuring chamber 14 is set to dispense 1 cup of rice, then in the embodiment described above, 3 cups and 1 cup of rice will be dispensed. , 2 cups of rice cannot be dispensed in one rotation operation. If it is desired to measure and discharge two cups of rice, it is necessary to open the discharge port 14a of the small measuring chamber 14 twice.

Therefore, as shown in FIG. 7, the base connecting the actuating pieces 22a and 22b of the interlocking arm 22 of the above embodiment is cut to prevent the actuating pieces from interlocking with each other, and the actuating piece 22b is removed. As a structure in which one end of is attached directly to the interlocking arm 22,
When the right side 6b of the operating lever 6 is rotated to the right, the large chamber shutter 11 is rotated and two cups of rice are discharged, while the left side 6a of the operating lever 6 is rotated to the left. For example, the small chamber shutter 12 can be rotated to discharge one cup of rice. In this way, by rotating the operating lever 6 left and right, the
It is also possible to adopt a configuration in which the measuring chambers are activated one by one.

In this way, the discharge ports of each metering chamber are not only opened one by one, but also any one and two or more are selectively opened, or one and two or more are opened one at a time. Can be configured.

The actuating member 21 is not limited to the link mechanism as in the embodiment, but may have other configurations.

Further, in the embodiment described above, each operating piece 22a, 22b of the interlocking arm 22 has two large and small shutters 11,
Although each outer surface of 12 is configured to be pressed, the configuration may be reversed.

Although two measuring chambers are formed in the embodiment, three or more measuring chambers may be formed, and even in that case, one operating lever 6 can perform a plurality of measurements. That is, all or more of the measuring chambers can be turned to the open position at the same time, and each arbitrary measuring chamber can be turned to the open position one by one.

According to this invention having the above structure, the measuring cell housed in the rice bin main body has two or more measuring chambers formed by the measuring cell main body case and the shutter, and is also provided with an operating member for operating the shutter. At one end of the provided lever shaft, there is a substantially flat operating lever extending left and right around the lever shaft, facing the outside of the rice bin body, and the operating lever can be rotated to the left or right. Since the configuration is such that any one or more of the discharge ports of the metering chamber can be selectively opened via the actuating member by a dynamic operation, a plurality of metering operations can be performed with one operating lever 6. Not only that, but compared to the conventional lever-type operation lever with downward movement, the installation space can be reduced. Moreover, since only one operating lever 6 is required, the number of parts is reduced and production costs can be reduced. Further, the shape of the operation lever 6 is made into a flat plate,
Since it is rotatable around the pivot point, it is convenient to perform weighing operations easily. Furthermore, the measuring cell 5 can be formed vertically in the axial direction of the lever shaft 17, and since only one operating lever 6 is required as described above, practical effects such as the ability to configure the rice bin body 1 to be vertically long with a long depth can be achieved. play.
